    Abstract: 本論文利用近場電紡織技術(near-field electrospinning,NFES),研究壓電奈米纖維,並且製作成奈米發電機(nanogenerator,NG ),主要重點為(1)利用近場電紡織技術大面積排列壓電奈米纖維製造發電機,(2)結合Cu-PTFE靜電發電機(triboelectric generator, TG),作為高輸出之混能發電機,(3)結合透明石墨烯電極製造全透明之混能發電機。以直寫(Direct -write)方式將壓電高分子材料聚偏氟乙烯(polyvinylidene fluoride,PVDF)利用NFES技術與XY精密位移平台將奈微米纖維(nano /micro fibers,NMFs )大面積排列在可撓性基底上製作成壓電奈米發電機,並且進行一系列訊號量測與驗證。為了使發電機更有效率的蒐集機械能,我們結合了靜電發電機成功讓混能式發電機有更高的輸出功率。另外,我們利用石墨烯作為電極,製造出全透明可撓的發電機,較於以往不透明的銅箔電極,全透明式有更好的應用,未來可以利用在智慧型穿戴裝置上做為自供電系統。;In this thesis, the near-field electrospinning (near-field electrospinning,NFES) technology was used to fabricate piezoelectric nano fibers and making nano-generator (NG). The mainly focused of this research on (1) Using NFES technology fabricated massively piezoelectric nano fibers as NG, (2) Combined Cu-PTFE triboelectric generator (TG) and NG as a hybrid generator, (3) Combined transparent graphene electrode to manufacture transparent hybrid generators. In this research, we demonstrated a polyvinylidene fluoride (PVDF) fibers could function as a suitable choice to act as a human motions sensors. In order to increase the output power, we development a combination of TG and NG as a hybrid device. Furthermore, we used graphene film as piezoelectric generator and triboelectric generator’s electrode to fabricate all transparent hybrid self-power sensor. The device demonstrated highly transparent and well flexible properties and the output voltage/current are measured as 6V/280nA under small mechanical force.
